Obtaining a value of N periods ago

[daborn-fox]

Hi,

I am hoping that someone might be able to help with a minor problem concerning values of N periods ago.

How would I get the value from, say, 6 days ago of the MA study below?

//The PMP
var vTMP = new MAStudy(3, 0, "HL/2", MAStudy.SIMPLE);

//The EMA of the TMP
var vEMA3_of_TMP = new MAStudy(3, 0, vTMP, MAStudy.MA, MAStudy.EXPONENTIAL);

I'd like to get the value of this vEMA3_of_TMP as it is today (now) and also as it was 6 days ago.

Can anyone help?

Many thanks,

[ACM]

In the case of your example you do that by adding a bar index when retrieving the value of the MAStudy using getValue() eg
myStudy.getValue(MAStudy.MA, barIndex)
Use 0 for the current bar and a negative number for prior bars
